30 to 1/2000 sec. and bulb.
Aperture
The aperture (or f-number) indicates
the size of the aperture opening in the
lens. The aperture opening is adjusted
by several aperture blades which
open and close to adjust the aperture
diameter. The aperture setting
displayed on the camera's LCD panel
and in the viewfinder can range
anywhere from 1.0 to 32, depending
on the lens attached to the camera.
The larger the f-number, the smaller
the aperture. And the smaller the f-
